'Il Specification forming part of Letters To all whom itma, concern:

Be it known that SIizLAH'B.v CoLLiNs, of` Lyndon, iniA the county ofWashtenaw and State of Michigan, have invented a new and usefulRevolving or Rotary Steaming-Box for Cooking Feed for Stock, &c.5 and Ido heref by .declare thatV the following is -a full, clear, and exactdescription thereof, reference being had .to the accompanying drawings,making a part of this specification. in which- Figure l is a verticalcentral section of the invention..l Fig. 2 is a top 'View 'of vtheadjust-v verse section of the cylinder or box C, showing the arrangement-of the elevating bars or Wings W. p l i p Similar letters Vot'reference indicate correj This invention consists, mainly, in theemployment of a revolving or rotary steamingso constructed and arrangedthat it may be revolved4 at intervals, or continually, ii' des ired,during vthe process, Whilethe steam is being forced into it fromvasteam-caldron or other generator. The several longitudinal bars fixed totheinside of the cylinder or box carry portions of the contents up ateach revolu tion, whence they are 'discharged gradually,y

as the bars ascend, thus exposing every particle to the direct action oftheinflowing steam, causing it to be quickly an d uniformly steamedthrough, thereby saving a vast amount of time more, when two ormorevarieties are cooked saves the time and labor necessarily requiredinits preparation in this respect-.'-Another feature of it consists in asimple and effectual method ot' conducting the steamv into the revolvingcylinder or box. l To enable others to malte and use my inventiornlwill' proceed Jto-describe its construe The cylinder or box G issuspended in a frame, B, or other suitable support, by means -oithejournal J, which is fixed to the head H by -Ineans s und by'tlieprojecting hollowjournal j' of the gearwheel G, which is 'xed tothe headH by screws s.

`thus compensating for any wear between the shoulder and the end oi' theslcevef, and its inner end may be protected by a funnelshaped cup,b,..to prevent the feed from working into and obstructing it. Therevolving cylinder C has a door, D,von one side, which is secured by ahinge,h, andan ordinary has'p and staple, p. The elevating bars or wingsWare arranged against the outer case and extend from one head to theother. The inner edge ot' these wings may be pivoted to the heads H andH by dowel-.pins, (shown by red dotted lines e, Fig. 3,) or otherwise,and they maybe kept in position .by adj Listing-pins indicated by redlines c. They may be set angling, asindicated by the dotted linesu, it'desired, so as toele-- -va'te the substance to a higher point beforedischarging it.- This position would be desirable in steaming grain.

The cylinder muy be madeeither four, six, eight, or any other number ofsquares desired,

Ainstead'ot being round. I l

Operation: The box C' is filled with pumpkins, potatoes, or grain, Sic.,or a mixture Aot' each, and the door D closed and secured by the hook.It is then supplied with steam by inserting the steampipc from auordinary steam-caldron into the conducting-pipe F, and

at intervals the box C is revolved a few times, by turning thecrank-shaft d, and as it revolves each wing W elevates a portion oi thecontents into the hottest partV of the chamber, thus changingl therelative positionof each particle and exposing it to the direct actionot the iniowing current of steam, whereby the bulk is more uniformly andthoroughly cooked, and inrnuch less Vtime than is possible in theordinary way, where the substance lies perfectly at rest on the bottomof the steambox, While the hottest part of the chamber is always at ltion every particle otsteam that entersthefl vtwo or more kinds arecooked together they become thoroughly mixed by the same process,

- which saves time in preparing the feed after itis cooked. Whenthesubstnncehassteamed p machines for cooking potatoes or other vegelongenough, the door l) otthe box is turned down :is indicated by the. fullred liues'w iri Fig. 3, and the adjusting pins withdrawn from `i thewings W, which are 11e-xt the door'. The lutter lis then opened, and thefeed discharged into e vut below; the said'two Wings swinging into theposition indicated bythe red lines,

i, thereby discharging whatever migl'xt other; wise lodge behind` them.

By withdruwingthe dow-els ve and pins e,

the several wings NV may be removed, when the boX may be used forsteaming hay, stalks, &c., to good advantage.

would also be well adapted to stenmin g clothes,

This adjustment which would be cleansed by the combined aetion of therevolving and steaming process. There may be a small perforated cylindersubstituted for the cup b, and extended across to and vconnected withthe head H iusniall tables for table use.

What I claim as my invent-ion, und desire toseeure by LettersPete1xt,isl The Wings or elevating bars W, which are mede adjustable anddetachable, substantially inthe manner and -tor the purposes speeitied,

i in combination with the rotary stemning-box C, as set forth.
